very sturdy tubes
Very thick and substantial feeling. Bit of a pain to install, but no flats.
A bit heavy.

Never had a puncture.
These tubes are very heavy. I couldn't believe how much slower they made me...about 1.5 mph off my normal 15 mph pace. I thought I was imagining it. Normally, I'm one of the fastest coasting down a hill in my group. These tubes made me last. I had to pedal to keep up. I switched them out for regular tubes and my speed returned instantly.
These might be good for race training...make you work harder.
